Description
[0001] The current application claims a priority to the U.S.
Provisional Patent application Ser. No. 62/574,319 filed on Oct.
19, 2017.
FIELD OF THE INVENTION
[0002] The present invention relates generally to a cover for a
torque strut engine motor mount. More specifically, the present
invention is a pair of covers that protect the rubber mount of the
torque strut engine motor mount from heat, chemical contamination,
and against other damaging forces that accelerate the normal wear
and tear of the rubber mount.
BACKGROUND OF THE INVENTION
[0003] A torque strut engine motor mount is utilized within a
vehicle to stabilize the engine within the vehicle. However, a
rubber bushing within the torque strut engine motor mount tends to
structurally fail overtime due to many different causes. The first
cause of failure is the effect of heat. More specifically, thermal
degradation is highly complex, depending on the material exposed
and the contact media. There is no single diagnostic effect, nor
visible externally when internal heat buildup causes thermal
degradation for the rubber bushing. As the temperature increases,
the rate of reaction of rubber degradation processes also
increases. Excessive exposure to heat leads a deterioration in
material properties and ultimately chemical degradation of polymer
itself thus structurally weakening the torque strut engine motor
mount. The second cause is the chemical contamination. More
specifically, engine oil, power steering fluid, transmission fluid,
gasoline, diesel, brake fluid, and other engine related chemical
contamination can degrade rubber bushing. The severity and effect
depends on the chemical and the chemistry of the rubber being
damaged, wherein deterioration of the rubber bushing structurally
weaken the torque strut engine motor mount. The third cause is
product design. More specifically, poorly engineered rubber bushing
tend to fail easily and quickly thus structurally weakening the
torque strut engine motor mount. Lastly, choosing the incorrect
material mixture and process. More specifically, having the
incorrect material mixture and manufacturing process can limit the
product life cycle of the rubber bushing thus structurally
weakening the torque strut engine motor mount.
[0004] It is an objective of the present invention to provide a
torque strut engine motor mount protective cover. More
specifically, the present invention is a protective cover that
encloses the rubber bushing of the torque strut engine motor mount.
Due to the fact the present invention is able to enclose the rubber
bushing, the present invention is able to keep out heat, dust, and
chemicals away from the rubber bushing. As a result, the present
invention is able to improve the reliability of the rubber bushing
thus extending the life cycle of the torque strut engine motor
mount.

DETAIL DESCRIPTIONS OF THE INVENTION
[0013] All illustrations of the drawings are for the purpose of
describing selected versions of the present invention and are not
intended to limit the scope of the present invention.
[0014] A rubber bushing of the torque strut engine motor mount,
generally placed within a strut eyelet of the torque strut engine
motor mount, often fails due to heat, dust, and chemical
contamination thus weakening the structural integrity of the torque
strut engine motor mount. Over exposure to these factors
accelerates the rubber degradation and deterioration of the rubber
bushing itself. The present invention is a torque strut engine
motor mount protective cover that insulates and protects the rubber
bushing against damaging forces that accelerates the normal wear
and tear. The present invention's design is a precise fit providing
extra support to the rubber bushing, reinforcing the torque strut
engine motor mount against vibration caused by engine acceleration
and braking, and protecting the strut eyelet of the torque strut
engine motor mount with its sealed technology that prevents
exposure to damaging factors.
[0015] The present invention comprises an outer rubber bushing
cover 1 and an inner rubber bushing cover 2 as shown in FIG. 1-2.
The outer rubber bushing cover 1 and the inner rubber bushing cover
2 delineate a cup-shaped bodies within the present invention so
that the outer rubber bushing cover 1 and the inner rubber bushing
cover 2 are able to conceal the rubber bushing. More specifically,
the outer rubber bushing cover 1 and the inner rubber bushing cover
2 are positioned offset from each other and concentrically mounted
to each other by a bolt that secures the torque strut engine motor
mount to the engine block.
[0016] In reference to FIG. 3-6, the outer rubber bushing cover 1
and the inner rubber bushing cover 2 each comprises a base plate 3,
a lateral wall 5, a bolt fastening eyelet 4, a first elongated body
7, a second elongated body 8, and an arm receiving cutout 11. In
order to delineate the cup-shaped profile for the outer rubber
bushing cover 1 and the inner rubber bushing cover 2, the lateral
wall 5 is perimetrically connected around the base plate 3.
Furthermore, a rim 6 of the lateral wall 5 is oppositely positioned
of the base plate 3 as the rim 6 is circumferentially positioned
around the lateral wall 5. The inner diameter of the outer rubber
bushing cover 1 and the inner rubber bushing cover 2 is larger than
the strut eyelet of the torque strut engine motor mount so that the
rubber bushing can be fully enclosed within the outer rubber
bushing cover 1 and the inner rubber bushing cover 2. In order to
properly place the outer rubber bushing cover 1 and the inner
rubber bushing cover 2, the arm receiving cutout 11 is positioned
on the lateral wall 5. More specifically, the arm receiving cut out
traverses into the lateral wall 5 from the rim 6 to accommodate a
shaft of the torque strut engine motor mount, wherein the shaft of
the torque strut engine motor mount connects the strut eyelet of
the torque strut engine motor mount to the frame of the vehicle.
The preferred shape of the arm receiving cutout 11 can differ
within the present invention as the preferred shape of the arm
receiving cutout 11 is determined upon the cross-sectional shape of
the shaft of the torque strut engine motor mount. For example, when
the shaft of the torque strut engine motor mount is circular, the
arm receiving cutout 11 is preferably shaped into a semi-circular
profile so that the outer rubber bushing cover 1 and the inner
rubber bushing cover 2 can be tightly placed around the strut
eyelet of the torque strut engine motor mount.
[0017] In reference to FIG. 3-6, the bolt fastening eyelet 4
traverses through the base plate 3 so that the outer rubber bushing
cover 1 and the inner rubber bushing cover 2 are able to provide an
opening for the insertion of the bolt. More specifically, the bolt
fastening eyelet 4 concentrically positioned to the base plate 3
and positioned in between the first elongated body 7 and the second
elongated body 8. The diameter of the bolt fastening is determined
upon the diameter of the bolt so that the bolt can be easily
inserted through the bolt fastening eyelet 4 and the rubber
bushing.
[0018] The first elongated body 7 and the second elongated body 8
function as retaining members and reinforcing members within the
present invention as the first elongated body 7 and the second
elongated body 8 collectively maintain the opposite positioning of
the outer rubber bushing cover 1 and the inner rubber bushing cover
2. In reference to FIG. 7, the first elongated body 7 and the
second elongated body 8 are positioned within the lateral wall 5
and diametrically opposed of each other. The first elongated body 7
is terminally connected to the base plate 3 and extends pass the
rim 6. Similarly, the second elongated body 8 is terminally
connected to the base plate 3 and extends pass the rim 6. More
specifically, the first elongated body 7 and the second elongated
body 8 each comprises a fixed end 9 and a free end 10 as shown in
FIG. 8. The fixed end 9 is terminally connected and positioned
normal to the base plate 3 thus resulting the free end 10 to be
positioned offset from the rim 6. Due to the extended shape of the
first elongated body 7 and the second elongated body 8, the first
elongated body 7 and the second elongated body 8 can be inserted
into an existing opening of the rubber bushing so that the outer
rubber bushing cover 1 and the inner rubber bushing cover 2 can be
friction-fitted to the rubber bushing. Resultantly, the first
elongated body 7 and the second elongated body 8 are able to
improve the structural integrity of the rubber bushing while
functioning as the retaining members.
[0019] The first elongated body 7 and the second elongated body 8
also function as flexible bodies within the present invention. As a
result, the first elongated body 7 and the second elongated body 8
are able to compensate the engine vibration. More specifically, the
flexibility of the first elongated body 7 and the second elongated
body 8 allow the rubber bushing to move back and forth during in
vehicle acceleration and braking.
[0020] When the outer rubber bushing cover 1 is utilized with the
torque strut engine motor mount, the first elongated body 7 and the
second elongated body 8 of the outer rubber bushing cover 1 are
oriented towards the base plate 3 of the inner rubber bushing cover
2. When the inner rubber bushing cover 2 is utilized with the
torque strut engine motor mount, the first elongated body 7 and the
second elongated body 8 of the inner rubber bushing cover 2 are
oriented towards the base plate 3 of the outer rubber bushing cover
1. Resultantly, the first elongated body 7 and the second elongated
body 8 are able to reinforce and secures the base plate 3 and the
lateral wall 5 with respect to the corresponding bushing cover. The
base plate 3 of the outer rubber bushing cover 1 and the base plate
3 of the inner rubber bushing cover 2 are positioned offset from
each other as the lateral wall 5 of the outer rubber bushing cover
1 and the inner rubber bushing cover 2 partially cover the strut
eyelet of the torque strut engine motor mount. Resultantly, the
base plate 3 and the lateral wall 5 are collectively able to
protect the rubber bushing with respect to the corresponding
bushing cover. The bolt fastening eyelet 4 of the outer rubber
bushing cover 1 and the bolt fastening eyelet 4 of the inner rubber
bushing cover 2 are concentrically mounted to each other through
the bolt that secures the torque strut engine motor mount to the
engine block.
[0021] Although the invention has been explained in relation to its
preferred embodiment, it is to be understood that many other
possible modifications and variations can be made without departing
from the spirit and scope of the invention as hereinafter
claimed.
